I did start another thread and I may aswell give my feed back from my local VW dealer Marshall (formerly Bridgwater VW).
My car is a 07 56plate. I have a small bubble on the front corner of my bonnet and rust coming through the boot lid number plate lights and handle. Arranged to meet the warranty chap this morning, took him 15 mins to manual measure the paint depth, average 100-150 on all panels measured. He then took photos on his own iPhone and said he will send off his report to VW. He said it may take a few weeks to get an answer. He seemed to imply that it would not cost me, but let's wait and see.
Regarding the customer service at this branch, I called back twice after waiting 3 days for a promised call back. It does seem that they are more interested in selling new cars rather than maintaining there present customers. Also today my car is having a service and cam belt change at a locally sourced Indy as this is saving me £200 on VW astronomical labour rates! I don't think it will make much difference to the resale value as it's now done 148000.
